To study this module you must declare the MSc in Mathematics (or another qualification towards which the module can count) as your qualification intention.
Normally, you should have also completed at least one of the entry modules for the MSc in Mathematics (F04), Calculus of variations and advanced calculus (M820) or Analytic number theory I (M823).
The subject of approximation theory lies at the frontier between applied mathematics and pure mathematics, since practical problems such as how to calculate special functions on a computer lead to theoretical problems such as 'which approximation method is best?'. Therefore you will need some familiarity with real analysis and linear algebra, such as that developed in typical undergraduate courses, and knowing the basic properties of metric spaces would also be useful.
All teaching is in English and your proficiency in the English language should be adequate for the level of study you wish to take. We strongly recommend that students have achieved an IELTS (International English Language Testing System) score of at least 7. To assess your English language skills in relation to your proposed studies you can visit the IELTS website.
If you have any doubt about the suitability of the module, please speak to an adviser.
